IMPROVEMENT lN eAs APPARATUS.

Specification forming part of Letters Patent No. 181,418, dated August 22, 1876; application led July 13, 1876.

To all whom it may concern:

Be it known that I, RICHARD DEAN, of Virginia City, Storey county, State of Nevada, have invented an Improved Gras Apparatus 5 and I do hereby declare the following description and accompanying drawings are sut'cient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention without further invention or experiment.

My invention relates to that class of gasmachines in which hydrogen gas is lirst generated, and then enrichedby passing it through a hydrocarbon 5 and my improvement consists in certain novelties in construction, as hereinafter set t'orth and specically claimed.

Referring to the accompanying drawing, Figure l is a vertical section ,taken transversely to Fig. 2. Fig. 2 is a vertical section taken transversely to Fig. 1. Fig. 3 is a horizontal section.

Ais an upright cylindrical case or shell, the interior of which' is divided into a carbureting-chamber, b, acid-chambers c, and gellerating-chambers d, by means of upper and lower diaphragms w y and a central vertical partition, z, which rises from the bottom of the case to the upper diaphragm x, which constitutes the division between. the carbureting and acid chambers. The gas generating chambers d d have strainers or false bottoms e and suitable side doors N N, with screw-caps, through which they are supplied with a quailtity of iron turnings. rlhe acid-chambers c c' are supplied with dilute acid through pipes f, which pass upward through the top ot' the case, and terminate Ain funnel-shaped cups. The carbureting-chamber is connected with generating-chambers by pipes gg, which open at their upper ends under a cup, h, for the purpose of spreading the'gas. rIhese pipes have stop-cocks i, operated by rods j, in order to admit the iiow ot' gas from either generator, which will be found necessary in case either lgenerator is closed for the purpose of either refilling or cleaning. The generatingchambers are furnished with cocks k, for the escape of air when the generators are first supplied with acid from the acid-chambers.

. Pipes P P allow communication between the acid-chambers c c and generating-'chambers d d. After the generator or generatingchamhers have been charged, the solution will be lforced more or less back into the acid-cham bers through the feed-pipes P P, according to the pressure of gas generated, thereby'automatically regulating the supply.

The carbureter is provided with a sponge, which is held in place by a perforated diaphragm, m, and saturated with hydrocarbon oil, which is introduced into the chamber through a pipe, a. o is a stop-cock, by which an excess of oil in the carburetor may be desame. The spaces between the perforated bottoms of the generating-chambers and the bottom of the case are provided with stopcocks r, for the purpose of drawing oi'sedinient and cleansing the apparatus.

I surround the case A with an outer proleft between the two for a packing ot charcoal or other suitable non-conducting substance, which will effectually prevent any obstruction arising from freezing. This protecting-case may be made ot' wood, iron, or.equivalent or suitable material, and is arranged to inclosel ot' carbureter and generators, the protectingcase S, with a sufficient space between the two cases for a non-conducting substance,.

substantially as specified. A

In `witness whereof I have hereunto set my hand and seal.
